SELF-CHECKING IVIOTORWTHEFT SIGNAL.

Application filed October 25, 1923. rSerial No. 670,775.

To all whom t may cof/1 com -Be it known that l, ROBERT C. ROTH, la citizen of the United States, residing at No. 24T lest 69th Street, in the borough of Manhattan, city, county, and State of New York, have invented a new and useful Self- Checking Motor-Theft Signal, and pray that Letters Patent may be granted to me for the improvement set forth in the following specification. Y

My invention relates to improvements in self checking motor theft signals, its object is to provide a self checking theft ind'n cator or signal on motor cars, trucks, boats or other vehicles, which will indicate, by the absence of a removable portion of the manufacturers registration number or mark integrally stamped or cast on a loose adjustable metal plate, hat possession of such cars, trucks, boats or other vehicles is prima facie unlawful, so as to ustify a demand by the police, for the production of the adjustable plate which contains the balance of the registration number or mark or other indicia of title, to prove ownership or lawful possession,

The object of this device and improvement is to permit the owner or lawful occupant of a motor car, truck, boat or other vehicle, when not in use, to remove the loose adjustable plate containing a portion of the manufacturei"s registration number or mark, and leave the portion of the registration number or mark stamped on the body of the car, boat or other vehicle, incomplete and conspicuous. The portion of the bony of the car. boat or other vehicle be` heath Jdie adjustable plate is painted in a vi vid color or conspicuously marked so as to attract attention, during the absence of the adjustable plate to the incomplete mark or number.

rlhis l obtain by the following device and combination, to-wit; a section of the manufacturers registration number or mark is integrally stampe.1 cast on or permanently attached to some conspicuous part of the motor car, truck, boat or other vehicle, the balancel of such registration number or mark being stamped or cast on a removable metal plate, to be affixed to the section of the registration number or mark on the body of the car, boat or other vehicle, and held in place by lugs, bars and a movable spring lug, thus forming and presenting when so atxed, the

complete manufacturers or other registration number or mark.

l obtained these objects by the device and mechanism illustrated in theaccompanying drawing in which; y

Figure l represents a side view of a motor car with the complete assembled registra-l tion number in position.

Figure 2 represents a detailed drawing of this security device with the loose adjustable section of the registration number removed.

Figure 3 represents the loose adjustable removable plate, which, when set in place, completes the serial car or vehicle registration number.

Figure 4 represents a cross section of the complete assembled device on the body of a motor car. n

Similar numerals refer to similar elements throughout the several views.

Fig. l represents the complete assembled registration number in position on a mot-r car. Although I want it understood that I do not confine myself to any particular position on a motor car or any other vehicle, on which it is placed, or to any particular mark, number, or indicia of title, 6 represents the portion of the registration number, integrally stamped or cast on or permanently affixed to the vehicle. l do not conne myself to any particular method of permanently attaching one sectin of the registration mark or number to the vehicle, but prefer it being stamped or cast in the body of the Tvehicle. 2 and 2 are bars permanently attached to the vehicle to keep the removable plate in position. 5 is the removable` plate set in position and held in position by bars 2 and 2 and the movable springv lug 1. l is a movable spring lug attached to the vehicle, which holds the removable plate 5 in position. 3, 3 and 3 indicate holes in the vehicle into which lugs 4, 4 and 4 of the removable plate 5 fit, when in position. 4,4, and 4 are lugs of plate 5 which lit into holes 3, 3 and 3 of the vehicle to hold plate 5 securely in position so it cannot slide. 7 is a spring in the back of the movable spring lug l, which gives free play to it. Movable spring lug l has on the lower side of its eX- tremity a pin which, when engaged in hole 8 of the removable plate 5 holds same securely in position. 8 is a hole or depression in the top of the removable plate 5, upon which the. pin on the lower side of the extremity ot the movable spring lug l rests when plate 5 is set in position. 9 represents the space upon Which the removable plate 5 rests when in position. Such portion of the vehicle (9) is to be painted in a vivid color or with a. conspicuous design, so as to attract the attention by and during the absence ot the removable plate 5, and give notice that possession ot the vehicle is prima facie unlawful,

thereby justifying a demand by the police for the production ot the adjustable plate 5, which contains the balance out the "registration mark or number, or other indicia ot title, to Aprove ownership or lawful possession. "Having described my invention, what l desire krto secure by Letters Patent and claim are:

l`."l`hel combination in a selt' checking motor theft signal, ot a section oit a registrationmark or number permanently carried by the body of a vehicle, in combination vvith a removable plate containing the remainder 'of such permanent registration mark or number, the removable plate being held in position by lugs set inholes'in the body of the vehicle and held in position by bars or stops and a removable spring lug at t'achefd to the vehiclel V 2.
